我知道这个问题经常被问到，但这个问题很不一样。日志文件只是多次发布上述异常而没有提到原因。日志文件如下所示

请帮助。我无法弄清楚问题
答案 0 :(得分：0)
我认为问题是由于这一行icon.recycle();，因为recycle()方法释放了与位图关联的本机对象，并清除了对像素数据的引用。所以试着像这样使用
states.addState(new int[] { android.R.attr.state_selected }, new BitmapDrawable(res, selected));
states.addState(new int[] { android.R.attr.state_enabled }, new BitmapDrawable(res, unselected));
icon.recycle();
